Abstract

Flutes or channels are provided at the ramped entryways of an orifice plate of a grinding machine head. Ramped entryways lead from the grinding surface of the orifice plate to one or more hard material collection passages located toward the center of the plate.
Providing flutes at the ramped entryway, rather than a smooth surface, helps control the flow of hard material into the hard material collection passages by creating friction to maintain hard materials in the entryway area once collected there, and by encouraging flow of hard materials toward the collection passage.

Claims (12)

1. A grinding machine comprising a rotating knife assembly and an orifice plate, wherein the orifice plate defines a grinding surface and has an inner section designed to collect hard material, at least one collection passage extending through the inner section, and at least one ramped entryway leading from the grinding surface to the at least one collection passage, wherein the ramped entryway is fluted.
2. The grinding machine of claim 1, wherein the flutes of the at least one ramped entryway are formed by milling.
3. An orifice plate for a grinder, comprising an outer grinding section having a grinding surface with grinding orifices, and an inner section designed to collect hard material, at least one collection passage extending through the inner section, and at least one ramped entryway leading from the grinding surface to the at least one collection passage, wherein the ramped entryway is fluted.
4. A method of grinding material that includes a combination of hard material and soft material, comprising the steps of providing a grinder having an orifice plate defining a grinding surface, wherein the orifice plate includes an inner section having at least one collection passage extending therethrough, and also includes a ramped entryway leading from the grinding surface into the collection passage, wherein the ramped entryway includes a series of axially extending flutes; grinding the material using a rotating knife assembly against the grinding surface of the orifice plate, moving the hard material inwardly along the grinding surface of the orifice plate by rotation of the knife assembly, and advancing the hard material along the ramped entryway toward the collection passage, wherein the axially extending flutes of the ramped entryway facilitate axial movement of the hard material toward the collection passage.
5. The method of claim 4, wherein the flutes of the ramped entryway are formed by milling.
6. A method of constructing a ramped entryway to a hard material collection passage extending through an inner portion of an orifice plate of a grinder, wherein the orifice plate includes a grinding surface, comprising the steps of forming an inwardly extending angled recess that extends from the grinding surface to the hard material collection passage, wherein the angled recess defines an outwardly facing bottom surface, and forming a guide structure in the outwardly facing bottom surface, wherein the guide structure is formed so as to extend axially along the bottom surface between the grinding surface and the hard material collection passage.
7. The method of claim 6, wherein the step of forming the guide structure in the outwardly facing bottom surface is carried out using a milling process that forms a series of axially extending flutes along the bottom surface.
8. A grinding machine having a grinder and an orifice plate, wherein the orifice plate defines a grinding surface and has a section designed to collect hard material, at least one collection passage extending through the hard material collection section, at least one ramped entryway defining a bottom surface leading to the at least one collection passage, and advancing means associated with the bottom surface of the ramped entryway for encouraging movement of hard material along the bottom surface of the ramped entryway to move the hard material toward the at least one collection passage.
9. The grinding machine of claim 8, wherein the advancing means also serves as a friction means for retaining hard material in the section designed to collect hard material.
10. An orifice plate for a grinding machine, comprising;
a grinding surface;
a hard material collection section designed to collect hard material;
at least one collection passage extending through the hard material collection section;
at least one ramped entryway leading from the grinding surface to the at least one collection passage, wherein the ramped entryway is defined by an inwardly extending angled recess that extends from the grinding surface to the hard material collection passage, wherein the angled recess defines an outwardly facing bottom surface; and a guide structure associated with the outwardly facing bottom surface, wherein the guide structure is formed so as to extend axially along the bottom surface between the grinding surface and the hard material collection passage.
11. The orifice plate of claim 10, wherein the guide structure comprises a series of generally parallel grooves in the bottom surface of the inwardly extending angled recess.
12. The orifice plate of claim 11, wherein the grooves extend the entire length of the bottom surface of the inwardly extending angled recess between the grinding surface and the hard material collection passage.
